Pros:
* I love the folding case and the professional look of the calculator.
* The writing tablet is a nice addition.
* The two-line screen has large numbers and characters, which makes it easy to read.

Cons:
* The manual is horrible! The manual has so many errors that someone is who new to calculators will have trouble using it.
* Errors include: many spelling errors, wrong key, mislabeling statistical equations (switching the slope (it should be a, not b), and the intercept (it should be b, not a), and describing some functions that are not even present (no conjugate function)
* s_x and s_y returns the population deviation, not sample deviation
